This section contains changes relevant to the installation of the
product, or to its Program Directory.
1. 2008/12/12 The CMS-based SSL server and its administrative
interface are supplied with the z/VM 540 installation
deliverable, in a disabled state. To enable and allow
for proper operation of the SSL sever, PTFs for the
APARs listed below must be applied:
TCP/IP APARs:
APAR Description
------- ----------------------------------------------
PK65850 SSL Server Enablement Support
PK73085 TCP/IP Server Updates for SSL Server Support
PK75268 AMPX036I Assertion Closing a Secure x3270
Session
CMS APARs:
APAR Description
------- ----------------------------------------------
VM64569 Performance Improvement for C Sockets on CMS
VM64540 Employ Socket Cancel() Without Reply()

Level 540 documentation.

This section contains general information, i.e., hints/tips.
3. 2008/11/25 Several TCP/IP for z/VM functions are Pascal-based, and
use VMCF communications to communicate with the TCPIP
server. Therefore, these functions cannot be reliably
used in conjunction with other applications that also use
VMCF communications (such as the CMS Utility, WAKEUP);
doing so may produce intermittent hangs during processing
or other unpredictable results.
The TCP/IP Pascal-base functions for which such problems
may arise are:
FTP HOMETEST LPQ LPR LPRM NETSTAT
OBEYFILE REXEC TELNET TESTSITE TFTP
See CMS Utilities APAR VM58540 for more information about
problems when using FTP in conjunction with WAKEUP.
See TCP/IP for z/VM APAR PQ87840 for more information
about problems when using REXEC in conjunction with
WAKEUP.
2. 2008/11/25 APAR VM64494, through its associated PTF, UM97540, is
used as the ordering mechanism for the current level of
the TCP/IP Function Level 540 RSU. This APAR/PTF will
be updated during every RSU cycle to indicate the RSU
level that is currently available through ISMD service.
The RSU can be ordered upon request by contacting the
Level 2 support group, or through the SRD (Service
Request & Delivery) function of IBMLink. Please see
the text of APAR VM64494 for more information, if
necessary.
Note: TCP/IP RSU maintenance is provided only as part
of the z/VM 5.4.0 "stacked" RSU.
1. 2008/11/25 When appropriate, the support center will open
informational APARs covering various aspects of TCP/IP
for z/VM. These APARs will cover installation and
maintenance specific information, information on using the
product, and other information that will often assist the
customer. Customers can search for these APARs by using
The product component ID (5735FAL00) and the keyword
TCPIPINFO. It's recommended that customers using TCP/IP
for z/VM review these APARs for information specific to
their needs.
